Application filed November 1 7, 19 24. Serial No. 750,347.

To all whom. it may concern.

ments to the beams of cultivators.

One of the objects of the invention is to provide a simple form of attachment which can be applied readily to a beam and which, when so applied, can be used for holding the shank of the engaged element at any angle, the shank being shiftable by the use of a universal connection with the beam engag ing portion of the structure.

WVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the in vention.

In the accompanying drawings. the preferred form of the invention has been shown. J

In said drawings:

Fig. 1 is a section on line 44, Fig. 2.

Fig. 5 is an elevation of a removable member of the attachment shown in Figs. 2

and 3.

' 10 which is provided in Referring to the figures by characters of reference designates a cultivator structure provided with beams B formed of metal and which, in the present instance,

are made up of spaced metal strips providing a structure which is stepped from end to end. In the form illustrated, it is desired to support the ground engaging elenient at the different steps of each beam so that the elements'on each travel in the same path. For the purpose of connecting a ground engaging element to the front portion of the beam. where the metal strips are the farthest apart, a devicesuch as shown in detail in'Fis 9,, 3

and 4- is preferably used. This inc udes a block 1 having a recess-2 in one end for the reception of one-of the strips 1) of the beam B, the said strip being held to the block by a bolt and into the end of the block; as shown in Fig. 3. The other strip of the beam, indicated at b is extended through theblock and held against one end" thereof by a bolt 4 which is extended downwardly through so the block and contacts with one side of the strip 6. A head 5' is extended from this last mentioned end block 1 and has a rounded socket 6 intersecting a channel 7,

which extends across the head are formedv in the end of the block 1 adjac'ent head 5 and are designed to receive tongues 9 extending from a clamping block rounded recess 11. This recess intersects a channel 12 which extends across the block from thetop to the bottom "thereof. Aball 13 is adapted to be seated between thehead 5 and the block 10- and a bolt 14 is inserta- 95 ble transversely through the head 5 and block 10 and, when tightened, will hold the tongues 9 in the recesses 8 and bind upon the ball 13 so as to hold it against rotation. The shank S of a tor blade is adapted to be fitted snugly within the balland may be adjusted longitudinally therein and held in any suitable manner not shown. This'block is adapted 105 shank 7.

beam will not 65 3 extending therethrough from the top to the bottom thereof. Spaced recesses 8 one face with a ground engagin element Gr which can be in the form of a cultiva- Where the attachment is to be applied to a single strip of the beam B as shown in Figs. 6 and 7 the structure can be modified by providing a solid block having a transverse opening 16 for the reception of the beam strip 79. A set screw 17 may be mounted in the block for engaging the strip 6 to hold the block against movement thereon. The block is cut away at one side to provide a recess 18 and another block 19 is adapted to be removably mounted on this recess. This block 19 is constructed in the same manner as the block shown in Fig. 5, the tongues 20 thereon being adapted to fit within recesses 21 in the block 15. Opposed rounded recesses 22 are formed in the two blocks to receive a ball 23 through which the shank S extends. A bolt 24: is extended transversely through the blocks and by tightening the same, said blocks can be nested securely upon the ball and to hold. it against rotation.

Instead of utilizing a set screw for holding the' atta chment to the beam, one end of the block can be provided with a transverse opening 25 to receive the beam as shown in Figs. 8 and 9. This end of the block can be split as at 26 and a bolt 27 can be extended 7 through the split portion so that by tightenmg the bolt, said split portion can be contracted to bind upon that portion of the beam engaged by the attachment. In either respect this modified construction is similar to that illustrated in Fig. 6 except, if pre ferred, these ends of the blocks remote from the beam can be reduced in thickness to pro vide flanges 28 for receiving the clamping bolt 29.

It has been found in practice that by providing a structure such as described, ground engaging elements canbe securely held to the cultivator beam at any angle to which they maybe adjusted. The attachments are simple, durable and efficient, and can be produced at low cost, and can be easily applied and removed without requiring the services ofra skilled mechanic.

What is claimed is engaging the ball seated within the recesses,

and means for drawing the blocks together at one end to bind them upon the ball.

2. An attachment of the class described including a block having a beam receiving 7 space extending transversely thereof, means engaging the block for binding it upon the beam, said block having a cut away portion or recess therein, a clamping block removably mounted in the recess, a tongue eXtending from the clamping block and projecting detachably into the first named block, a ball interposed between and projecting into the blocks, and means for drawing the blocks together to bind upon the ball, said ball constituting shank holding means.

3. An attachment for a cultivator or the like including a block having a transverse beam receiving space, means engaging the block for binding it upon a beam within said space, said block having a cut away portion forming a recess, a clamping block removably seated in the recess, a tongue projecting from one end thereof and into the first named block to hold the blocks assembled at one end, a ball interposed between and projecting into the blocks, said ball being ad justable angularly in any direction about its center, there being a diametrical shank receiving opening in the ball, and means engaging the blocks for binding them upon the ball.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses.
